1 h This invention relates to lasting machines and has more particularlyin view' the provision of certain improvementsin a machine shown anddescribed in an earlier application of mine, Serial No. 189,407, filedon October 10, 1950. The invention is accordingly herein disclosed asapplied to an organization .of that character, but it is to be,understoodthat in various, novel aspects it is not limited to thisillustrative embodiment. I 1 The machine shown in the above-mentionedapplication is a machineior lasting the ODDOSi-te sides of the ballportions of shoes extending from the toe portions to the shank portions.It includesapair of grippers for gripping and pulling the upper at .theopposite sides ofthe ball portion ofoeach shoe respectively, and meansfor thereafter wiping the marginal portion of the upper inwardly over aninsole on the last into position to adhere to the insole throughthe/ac.- tion of cement. The wipin means includes at each side of theshoe a pairoi wipers arranged to extend continuously, each beyond theother, along the side or the shoe and relatively movable in directionslengthwise of the shoe while maintaining such continuity, the machinehaving means positioned as determined by engagement with the toe-endface of each shoe when the shoe is. presented to the machineforcausingsuch relative movement of the wipers thereafter to take placein the course of their operative'move ments before they arrive in'positions to act on the upper and for thereby determining t e CE tancelengthwise of the shoe of the engagement ofthe pairs of wiperswith theuppe'r in accordancewith the position of the toe-end face of the shoe.Since the operator, in presenting each shoefto the machine, positionsithlength'wi'se by sight with reference to the side grippers, the toe--end faces of shoes of different sizes are different- 1y positioned, andaccordingly the wipers are so controlled as to vary the distancelengthwise of the shoe of their engagement with the upper'in accordancewith the size of the shoe.

The present invention, in one aspect, provides improved means forcontrolling the wipers in such manner as to accomplish the aboveresult.In the construction herein showriffthe wipers which extend nearest tothe toe end ofthe shoe are moved more or less in directions lengthwiseof the shoe relatively to the other wipers at the time ,when'the shoeis. presented to the machine by a member connected to them 'an'dengagedand moved by the toe-endface of the shoe. They are, moreover, thus movedrectilinearly instead 2 of being swung about. axes extending heightwis'eof the shoe as are the corresponding wipers in the earlier construction-The connections beward parallel relation and thereby move those wipersto some extent reversely lengthwise .of-the shoe relatively 'to theother wipers, thereby coun I teracting suchtendency as they may'have,bee

cause of the directions in which they are'moved inwardly over the shoebottom, to deflect the margin of the upper unduly toward the toe end ofthe shoe. p l L The invention furtherprovides wiping means havingespecially in view an improvement/in the results obtained in wiping theupper inwardly over the insole in locations where the bottom of the shoecurves heightwise of the shoe toward the shank portion beyond the ballline. In the construction shown the wipers above referred to asextendingnearest to thetoe end of the shoe are arranged to overlapportions of other com-v paratively thin wipers made of resilientlyflexible metal and having portions arranged to extend beyond thefirst-mentioned wipers toward the" heel end of the shoe for engaging-theupper in the above-mentioned locations beyond the ball line. Theseportions of the flexible wipers have normally a curvature approximatingthat of the corresponding portions of theshoe bottom, but such as toinsure that in moving inwardly from positions outwardly retracted beyondthe edge of the insole they will not displace the marginot the insole.To render those portions of the wipers properly effective in wiping theupper inwardly and in pressing it on the insole, the machineis providedwith means for automatically bending them heightwise of the shoetowardthe shoe bottom in predetermined time relation. to theirin- Wardmovements and for thus conforming them to the contour of the bottom ofthe shoe. The bending'thereof is timed to take place only after. theirwiping edges have passed the extreme edge of the insole in their inwardmovements, but prior to the completion of their inward movements, so

that they will have an inward wiping action on the upper after beingfully conformed to the contour of the shoe bottom. .Inthe constructionshown the bending means comprises fluid-operated devices which arefmovedinwardly with the wipers and, though subjected tofiuid pressure, areprevented by latches from operating until the proper time, the latchesbeing then re- 3 tracted in response to the inward movements of thewipers to cause the bending thereof as above described.

To render the above-mentioned heelwardly extending portions of theflexible wipers properly effective it is important that the portions ofthe shoe on which they act shall be firmly supported against thepressure applied to the wipers by the bending means. In the machineherein shown the shoe is positioned bottom upward by means engaging thebottom of its fore part, and it is clamped against this positioningmeans by an upwardly movable toe rest To insure further against anytipping of the s oe such as might affect unfavorably thje'a'ction of theabove-mentioned flexible w'pers' thereon, there is provided a memberwhich adjusts itself to the back cone (or heel end) and the front coneof the inverted last underneath and is thereafter securely held againstdownward movement in supfiorting relation to the last. As herein shown;in memb r comprises a plate mounted to tip: yieldingly about an axisextending widthwise or the last and further so supported yieldingly asto permit it to be depressed bodily more or less byengagement of thelast therewith when the slroefis presented to the machine. I At a prede-I tar-mined time in theoperation of the machine a age. qn iuw r y s eminto supp ing relation to the plate and is positi"'ely loclzed against'rev erse downward movene rby means wh'ich is rendered effective by thefist id rm et' i we i es It has been found that right and left shoes arebetter supported by the toe rest against the pressure applied a theretothe wipers at the oppos te sides ofthe forepart or the shoe bottomfi'fthe toe rest is" shifted to some extent in. directions withwise of theshoe to different peep tie for rightand left shoes respectively. Thiserisesnon the fact that the toe rest includes a shoe-engaging membermounted for tipping move"ent about an axis extending lengthwise of eachshoe in response to engagement of the shoe" therewithto conformto thelateralsl'ope ofthe top of the forep art' of thes hoe, and this memberwill more readily tip to conform to right am left shoes if it is thusshifted to different pd tions for the different shoes prior to engage:merit therewith.- In accdrdano'e with the dis ensur the earlierapplication the "machine hereiii hown s provided for aiitomaticallyshifting the opposite side grippers to different positions for operatingalternately on right andleft shoes in successive cycles of oper ationsof the machine; and for shifting the toe rest as above describedtheconstruction herein shown includes connections between it are the meansfor thus shifting the grip ers to cause it to be shifted as desiredsimultaneously with the grip'pers. v I v V "The above and other featuresof the invent-ion, including various noveldetails of construc ti andcombinations of parts. will now be more particularly described withreference to the ac edmasfi mg drawings and thereafter pointed out iiithe claims;

In view of the disclosure I in the above-men: tionedapplication, thepresent description will be confined to such portions of the machine asit is necessary to refer to for an understanding of the invention.

For positioning the shoe heightwise in the machine there is provided ashoe rest member 2 (Figs. 1 and 1) having on its lower end two presserfeet 4 (Fig. 8) spaced apart widthwisjeof the shoe and provided withteethfor engaging the insole at the ball portion of the shoe, thismember corresponding to the member l0s'hown in theabove-mentionedapplication and being supporte'd and controlled in the same manner asthat member. Accordingly, the member 2 is held stationary when the shoeis first engaged there with and during thegreater portion of the opera;-tion of the -machine. Furtherto assist in son: tioning the hoe there isprovided another shoe rest member 6 on which are two downwardly elitending bosses 8 spaced apart widthwis of the shoe; and arranged to engagethe toe-end portion of the insole' these bosses in the constructionherein, shown also having insole-engaging teeth thereon. The member 6corresponds generally to the member 54 shown in the above-mentionedapplication, and it ispivo'tally mounted at its rear end on a pin 1 llsupported in upstanding lugs on a slide 14 which is guided for'forwardand rearward, movements a holder 16 secured to a ill on the frame.Spring means hereincasting after described tends to move the slide l4 ina forward direction, its forward movement being limited by itsengagement with a stop pin 22ml the holder [6. Adjustab1y secured to themember 6 by a screw 21 is a member 26 arranged to be engaged by thetoe-end face of the shoe when the two spring-pressed pins 32 (Fig. :1)which are mounted in a block 34, this block'being pivotally mounted on a'pin 36 supported on the lower ends of two links 38, only one of whichis herein shown; These links correspond to the links 84 shown-in thepreviously mentioned application: and are controlled generally in thesame manner as those links. Initially, therefore, and during the greaterportion of the operation of the machine, the

links 38,- and accordingly the'block 34, are'held against upwardmovement. In the construction herein shown the upper face of the member6 has two rows of teeth thereon, between which rows the pins 32 engageth membenandthe lower face of the block 34 also hasteeth thereon whichare initially out of engagement-with the teeth on the member 6 by reasonof the action of the spring-pressed pins 32 onthi member, thuspermitting the rearward movement ofthe-member 6 by the shoe whenthe shoeis presented to .themachine. When the shoe is pressed upwardly againstthe shoe rest members 2 and 6, as hereinafter described, the member 6 isswung upwardly against the resistance of the pins 32 by thepressure ofthe shoe thereon, thus causing the teeth on this member to engage theteeth on the block .34. In this manner the member 6 I is locked againstfurther rearward movement for .apurpose hereinafter explained.

While the shoe is still held in. the operators hands after he haspresented it to the machine it is automatically positioned widthwise inproper relation to the lasting instrumentalities by side clamps 40(Figs. 1 and 8) whichengage it at the .oppositesides of the forepart.These side clamps differ only in details which need notbe describedfrom; clamps provided for .the same purpose in the machine shown in theearlier application.

They; are supported on levers 42 which are mounted to swing widthwise ofthe shoe an are operated by fluid-pressure means in the same manner ascorresponding levers I 04 shown in the earlier application. s

After the shoe has been positioned laterallyzby the clamps 40 it ispressed upwardly against the shoe rest members 2 and 6 by a toe rest 46(Figs. 1, 4 and 7). This toe rest comprises a rubber pad ;.48 having ashoe-engaging face which i convexly curved lengthwise. of the shoe andis slightly concave widthwise of the shoe, the pad being secured toaholder 56 which is guided on a block 52 for .tipping I movements aboutan axis extending lengthwise of the shoe to'permit the pad 48 to adjustitself in this manner to the shoe. For this purpose the lower face oftheholderiis convexly curved about that axis and rests on rolls 54supported by the block, only one of these rolls being visible in thedrawings. Flanges 56 on the holder are-engaged by flanges 58 on theblock to retain the holder in position on the block, and the tippingmovement of the holder is limited by engagement of the head of a screw60 thereon with shoulders 62 on the block. The block 52 is mounted on aT-shapedguide 64 for rectilinear movements in directions widthwise ofthe shoe, this guide having a depending portion 66 mounted in an upwardextension 68 of a piston Ill-for rectilinear movements in directionslengthwise of the shoe. A screw 12 threaded in the extension 68 has aconical end extending into a V-shaped groove I4 in one side of thedepending portion of the guide 64 o secure the toerestin 6. any positionofadjustment lengthwise of the shoe- Means provided for adjusting theblock 52 widthwise of the shoe along the guide 64 will be hereinafterdescribed, such movements of the block being limited by a screw I5 whichis threaded therein and extends into a slot I6 in the guide 64.

The piston This movable upwardly in a forwardlyinclined direction in acylinder I! by operating fluid admitted to the lower end of the cylindersubstantially at the beginning of a cycle of operations of the machine,as in the machine described in the earlier application, such upwardmovement of the piston being effected against the resistance of a pairof return springs 18 only one of which is shown. In this manner the toerest is moved into engagement with the shoe on the top of the forepartand clamps the shoe against the shoe rest members 2 and 6, the member 6being swung slightly upward by the pressure thus applied to the shoe tocause the teeth thereon to engage the teeth on the block.

Each of the grippers 28 (Fig. 8) comprises a pair of-upper-gripping jawsand 82 associated with a holddown 84 which is arranged to engage themargin of the insole in the upper-pulling operation to provide apurchase on the bottom of the shoe for a fluid-operated lever by whichthe gripper is moved upwardly to pull the upper, as disclosed in detailin the previouslymentioned application. The two grippers are thus partsof gripper and holddown units 86 (Fig. 6) mounted to swing about pins 86extending heightwise of the shoe for differently positioning thegrippers and holddowns in operating on right and left shoesrespectively. That is, thegripper which is to grip and pull the upper atthe inner side of either shoe is positioned nearer the toe end nectedatits opposite endsrespectively to the different units through rods 94.It will 'thusbe seen that by the swinging of the-lever 98 in ondirection or the other the two units are swung simultaneously about thepins 88 in opposite directions respectively lengthwise of the shoe. Thelever an is thus swung automatically near the end of each cycle ofoperations of the machine to shift the grippers and holddowns topositions for operating on a right shoe in one cycle and to positionsfor'operating on a left shoe in the next cycle. For this purpose thereis pivotally connected at one end to the lever 90 another lever 96having therein a slot 98 through which extends a pin I66 providing anadjustable fulcrum for the lever 96 for varying the amount of movementimparted to the units 86. At its other end the lever 96 is connected bya link I02 to a crank pin I04 on a gear wheel I06 in'mesh with a largergear wheel I08. Mounted to turn with the gear wheel I08 is a' disk IIIlhaving thereon four pins II 2 spaced equal distances apart successionand thereby to turn the disk M each timeniiistance such as to imparttothe crank pin .1104 a movement of 180. Aspiring-pressed pin I24 in thepiston "I 16 engages a fiat .iaceon the latch [22 and holds the datchnormally upraised in the .position shown in :Fig. 1., Upon forwardmovement of the piston by theoperating fluid the latch is deflecteddownwardly by the next pin H2 until it snaps upwardly .into position toconnect with :this pin, after which it :acts to turn the disk I it asabove described in response to rearward movement of the piston effectedby springs 128 connected to :the pin l l8. .The movements of the pistonin opposite directions are limited by engagement of the pin :8 with thecylinder Id at the opposite ends of the slots J10. To hold the disk H0againstdisplacement when the latch is moved forwardly into posi-v tionto connect with the next pin H2, there is provided a spring-presseddetent I28 :having a V-shaped end arranged to enter one or another offour V--shapedrecesses I30 in the periphery of thedisk.

- There is tfurther provided means whereby the operator may at=any timeprior to the operation of .themachine on a shoe-shift thegripper andholddown units 86 manually into positions for operating on a right shoeor a left shoe selectively. .Fo'r thisipurpose a forwardly andrearwardly extendingrod 132 guided in the frame and in abracket 434 hasa flattened rear portion formed .to' ser-ve as a latch [36for engagingone or :anotheaof the pins 1 I 2 and for thereby turningithe dish 1.16.in the :same direction in which it is turned by the latch I22. Thedisk. is thus-turned a quarter revolution by forward movement of the rod432 against the resistance of a return spring .(not-shown). When thelatch isreturned by this spring it is deflected upwardly by engagementwith "the next pin H2 until it arrives in position to connect with thatpin. To-permit suchupward deflection-of the latch the flattened portionof the rod 4.3-2 extends through a ver- .tical slot in the bracket 134.It will be understood that when the disk It!) is thus turned manuallythe pins H2 pass idly over the latch LZZ-and that when-the disk isturned bythis. latch the pinspass idly under the latch I36.

.Asis well known, the top of the forepartof ;a last is-usually somewhathigher near the inner side .of the last thannear the outer side,especially in .a-location comparatively remote from the end of the .toe.To aiiord better insurance 'that the .toe rest 4.6 will support the shoe'aswwell against pressure applied .theretoby the wiping means at the.outer side of the shoe bottom as against that applied at the innersideof theshoe bottom, mechanism is provided for shifting the toe restlaterally to difierent positions for rightandleft shoes, so that the toerest pad will more readily .tip .into a position conformable to thelateral slope-of the top of the forepartcf the shoe upon contact withthe shoe. .This requires that foresupporting aright shoe positioned inthe machine the toe-rest be shifted toward the. left (Fig. .8') and thatfor supporting .a leftshoe it beishifted toward theright. For thusshifting the toe-rest there is provided a flexible wirecable 138 securedat one end toastud M0 mounted on :the block 52 which is movable ashereinbefore described in directions widthwise of the shoe along theguide .64. The cable l.3-8-extends through a flexible guide I42 one endof which isfast in a clamp M4 ;secured tothe upward extension 68 .ofthe'jpiston 10. The other end'of the cable-isslidingly mounted in'thelower end of a pin I46 (Fig. '1) extending downwardly from the left-handend of the gripper-shifting lever 98. Secured by setscrews to the cableat the front and rearof the pin .146, respectively, are collars I48.When the-lever-Qfi, therefore-is swung to shift the gripperland-holddown units '86 to positions for operating .on a rightsshoe, thepin 146 acts-on the rear collar 21.48, as shown, to move the .cable .138in the direction to-shift the toe'rest '46 to the position appropriatefor that .shoe. Similarly the movement of the lever to shift the units:86 into positions .for a'leftzshoelcauses the pm 146 to act on theother collar 8 and thus to shift the toe rest to the position :for thatshoe. .As shown in Fig. 1, "the collars 148 are so positioned on thecable ,as {to provide" for some lost motion before the pin H6 becomes:effiective to shift the toe rest, the movement of the-toe rest in eachdirection being lim ited by the screw 15 and the slot '16 For-wipingthe'margina-l'portion of the upper inwardly over the "insole .intoposition to adhere to the 1113016310113thG' OPDOSltBSideSiCfth ballportion of 'each shoe after the upper has been pulled :by upwardmovements :of the grippers :18 the machine is provided :with wiperscarried 'by levers [50 (Fig. 2) which are mounted to swing widthwise ofthe shoe about studs i152 and are connected together -by teeth J 54 toequalize their movements, these levers corresponding to the levers 542shown in the previously mentioned application and being operatedsimilarly to those levers by fluid-pressure means 'at the required timein the operation of the machine. In the construction herein shown thereis secured'to each lever 1'50 underneath, in a location sspaced'f-romthe lever, a-plate' il:-56 (Figs. f3 :and '9) and guided on'the topofzthis'plate for rectilinear movements in directions lengthwise of theshoe is a wipercarrying plate I58. 1Secured bytwo screws 1:60 to anouter downwardly extending portion of *the plate |-58.is a wiperp ate orwiper cs2 arranged to extend :inwardly toward the shoe :under the plate[56in contact therewith,-the wiper f62having .a wiping edge extendingstraight lengthwise of the shoe for engagement with the upper. The innerportion'of'the wiper 1'62,- i. e., the'portion'losated nearest the shoe,is siightlycfisetzupwardly from otherportions thereof, the plate l56havin'g therein ia'recess l6i4 (Fig '9) to receive this offset portion'Of. the wiper. This construction provides in thewiper 162 a recess (66(Fig. 3) and-bridging this :recess is another thinner wiper plate 168which :is resiliently flexible. As shown in :9, the inner edgeoftheplate lBS-is slightly spaced in an outward direction from the inneredge of the Wiperrltlandas more clearly shown ini'ig. 3 the inner edgeportion of :the plate 188 isrin engagement .withthe lower face ofthewiper 1B2. The plate I 68 :is secured to the wiper 152 intlocationscomparatively remote from the shoe byatwo studs lflflgtheportionof'theplate'in which these studsrareilooated being spaced somew'hatbelowthewwiper 1.62. It will thus be seen that in .the'vliping operation theupper is engaged by the edgezofithe'wiper l 62 slightlybe'fore it isengag'ed bythezplate Hi8, portions of thisplate being yieldableaheig'htwiseoi the shoe-relatively to-the'wiper 1.62 to :conform betterto the-contour of the shoe bottom. IIo increase the flexibility ofthe-plate 1.68 it :hasgthereima series ot'slots [:12 extending widthwiseof the shoe.

Forlpositioning the-wipersfitzlengthwiseofthe slice the. slidable platesi5 8 to which theyare-secured are connectedibylinks 1H (Fig-*2) to the 9upstanding lugs I 2 on the slide I4 which is guided as hereinbeforedescribed for movements lengthwise of the shoe in the holder I6. Theplates I58 are controlled by springs I16 connected to them and to thecorresponding levers I50, these springs tending to move the plates andthe wipers I62 thereon, together with the slide I4, forwardly toward thefront of the machine. Such movements of the plates are limited whenthere is no shoe in the machine by contact of the slide I4 with thepreviously mentioned stop pin 22. When the operator moves the slide I4in a rearward direction, as hereinbefore described, by engagement of thetoe-end face of the shoe with the member 26, until the sides of the ballportion of the shoe are in proper relation to the grippers 28, rearwardmovements also are imparted through the links I14 to the plates I58 andthe wipers I62 to position these wipers lengthwise of the shoe. Thisdetermines the distance of the wipers I62 from the end of the toe, andit will be evident that this distance will be the same for differentshoes regardless of such variations as there may be in the positions ofthe shoes lengthwise as they are presented to the machine by theoperator. It will be further evident, however, that the distance of thewipers I62 from the end of the toe may be varied by adjusting thetoeengaging member 26 relatively to the shoe-rest member 6 on which itis mounted.

The studs I52 about which the levers I50 are swung are so located thatin wiping the upper inwardly over the insole the wipers I62 havecomponents of swinging movement lengthwise of the shoe toward its toeend. As illustrated in Fig. 2, however, the links I14 diverge from eachother in directions toward the heel end of the shoe, and accordinglythey approach a parallel relation as the wipers are swung inwardly. Theeffect of the inward swinging movements of the links, therefore, is toimpart to the wipers I62 and the plates I68 thereon movements of someextent lengthwise of the shoe toward its heel end as they wipe the upperinwardly over the insole. This serves to counteract any tendency for thewipers to deflect the margin of the upper unduly toward the toe end ofthe shoe. In this operation the slide I4 is locked against rearwardmovement by the teeth on the members 6 and 34 to prevent any bodilyrearward displacement of the links I14. v To cooperate with the wipersI62 in wiping the upper inwardly near the ball line, and for wiping itinwardly also in locations where the bottom of the inverted shoe curvesdownwardly in a heelward direction beyond the ball line, the machine isfurther provided with additional wipers I18. Each of these additionalwipers comprises a thin resilient metal plate more readily flexible thanthe wiper plate I68 and secured by two screws I80 to the supportingplate I56 in a position spaced from the latter plate. A por-" tion a ofeach wiper I18 (Fig. 9) is arranged to lie between the shoe and theplate I68 with its edge in contact with this plate but elsewhere spacedtherefrom to permit it to be readily flexed in response to the pressureof the shoe thereon in the wiping operation. Another portion b of thewiper I18 xtends in a heelward direction for wiping the upper inwardlyin a location where the bottom ofthe inverted shoe curves downwardbeyond the ball line, and this portion of the wiper has a normalcurvature heightwise of the shoe somewhat less than'the' curvature ofthe corresponding portion of the 10 shoe bottom to insure that as itstarts to move inwardly there will be suflicient clearance between itand the edge of the insole to prevent displacement of the insole. Torender it properly eifective in wiping the upper over the insole and inpressing it on the insole there is provided means for automaticallybending it downwardly after it has passed the edge of the insole in itsinward movement. For this purpose there is secured on a lateralextension of each lever I50 a casting I82 (Figs. 2 and 3) formed toprovide within it a cylinder I84 in which is mounted a piston I86.Carried by this piston is a pin I88 which extends through slots I90 inthe opposite sides of the cylinder casting, the movements of the pistonin opposite directions being limited by engagement of the pin with thecasting at the opposite ends of the slots. A spring I92 connected to oneend of the pin and to a member I94 fast on the casting I82 tends tomovethe piston in an outward direction and holds it initially at thelimit of its outward movementl Mounted on the pin I88 is a rod I96 whiche'xtends through the open inner end of the cylinder I84 and adiametrically reduced portion of which is slidably movable in a trunnionblock I98 pivot ally mounted on one arm 200 of a bell-crank lever 202,the bell-crank lever being mounted for swinging movement on a pin 204supported in an upstanding lug 206 on the lever I50. Extending aroundthe rod I96 between a nut 208 threaded on the rod and a flange 2| 0 onthe trunnion block I98 is a compression spring 2I2, and threaded on therod on the opposite side of the trunnion block from the spring is a nut2I4 arranged to engage the trunnion block Pivotally connected at itsupper end to the other arm 216 of the bell-crank lever 202 is a bar 218which extends downwardly through an opening in the wiper-carrying plateI56 with its lower end in position to engage a small block 220 securedon the portion b of the wiper I18. By operative movement of the pistonI86, therefore, the bar 2I8 is moved downwardly at the proper time tobend the portion b of the wiper I18 in a down ward direction and thus tocause it to press the portion of the upper which it engages against theinsole.

For operating each piston I 86 fluid underpres sure is forced intotheouter end of the cylinder I84 through a conduit 222 communicatingthrough a flexible tube (not shown) with the source of fluid supply, theadmission of the fluid to the cylinder being controlled by the samevalve(not shown) which, in accordance with'the disclosure of the previouslymentioned application, admits fluid to the gripper-operating means tocause the grippers 28 to pull the upper. Operative movement of thepiston by the fluid,

however, is prevented until the wiper I18 has thereafter arrived in apredetermined position relatively to the shoe. For this purpose there"is pivotally mounted on a pin 224 in the casting I82 a latch 226 whichinitially engages one end of the pin I 88 in the piston to hold thepiston against operative movement. Pivotally connected to this latch isa rod 228 extending through an opening in a bracket 230 fast on theframe of the machine. Between this bracket and a shoulder on the rod 228adjacent to its pivotal connection with the latch is a compres sionspring 232, and threaded on the outer end portion ofthe rod is a nut234. As illustrated in Fig. 2, the spring 232 initially holds the latchZ26 inpositi on to engage the pin I 88 and preventmovement of thepiston, and the latch is held in this relation to the pin until thewipercarrying lever I50 has moved far, enough to cause the nut, 234 toengage the bracket 230, whereupon the latch is caused to release the pinin response tocontinued movement of the lever, thus causing the bar 2l8to be forced suddenly downward. Preferably, the nut 234 is so adjustedthat this downward movement of the bar takes place immediately after thewiping edge of the portion bof the wiper I18 has passed the extreme edgeof the insole, so that. this portion of the wiper will be conformed tothe contour of the shoe bottom and will apply its downward pressure tothe upper prior to the completion of its inward wiping movement. Inpressing the wiper down on the insole the spring 2l2 will yieldinresponse to resistance of the shoe to the downward movement. of thebar. 2H3, the rod I 96 sliding in the trunnion block I98. When thefluidunder pressure. is later released from the cylinder 84 the piston W6 isreturned: by the spring Hi2, after which the latch 226 is returned. bythe spring 232; toits operative positionin. response to return movementof the lever. I50. The" portion b of each wiper H8 extends farenoughtoward the heel end of the shoe to overlap to someextent' a portion ofthe upper previously lasted at the shank. portion of the shoe.

From the foregoing. description it will. be evident that thewiper Hi2(with itsplate l-SB) and. the wiper H8 at each side of the shoe. arearranged to extend continuously, eachbeyond the other, lengthwise of theshoe,v and that the wiper [82- is moved relatively to the wiper H3without afiecting such continuity whenit is positionedas determined bythe shoe in the presentation of the shoe tothe machine. It will iur-therbe-understood that it is in consequence or such positioning movement ofthe wiper H52 that. the distance of the engagement. of the; pair ofwipers [.62 and HQ with the shoe: lengthwise thereof is. determined inaccordance with the position of the toe-end face of the shoe and willvary for shoes of difierent sizes. The wipers at each side of the shoeare maintained; in a heated condition byelectrical heating, units 236:mounted in the wiper-supporting plate I56, heat being conducted fromthisplate to the wipers.

In order torender the: portions 17 of the flexible wipers I18 properlyeliective in pressing the upper down on the insole, the machine. is:provided with further means forinsuring. against any tipping of the shoeas a result. of the pressure thus. applied. For the purpose in view aplate 2387 (Figs, 1 and 4-): which is curved to present a convex upperface extending lengthwise of the shoe is: secured to rectangulanportions239 (Fig. 4a) of a p n 240 mounted for tuming movements about an axisextending widthwise of the shoe in. the frontendsoi two parallelrearwardly extending arms 242 which arepivotally mounted at their rearendsonthe casting 18- for swingingmovements heightwise of the shoe. Aspring 244iconnected to one of the arms and to a collar- 246 fast on thepin- 24! holds: the plate 238 normally in a position such as.illustrated in Fig. 1 while permitting it to be tipped about the axis ofthe pin 24!) in either direction. Pivotally connected at its upper endto one of the arms 242 is: a rod 248 extending downwardly through amember 2.5.0 mountedv in thecy-linder casting H. Betweenthe member-2,50and a collar 252 fast, on, the lower end of the. rod 248 is acompression spring. 2:54; and

between the member and another such collar 258 fast on the rodnear itsupper end is another compression spring 258. Through these springs thearms 242 are held in a state of balance at such a height that when theshoe is presented to the machine they will be moved downwardly to someextentagainst the resistance of, thecomparatively light spring 258 byreason of engagement of the last with the plate 238. This plate swingsin one direction or the other about the axis of the pin 240 until it isseatedboth against the top. face of the back cone (or heel end). 6 ofthe last. and againstv the top of. the front cone d of the last, asillustrated in Fig. 4. To support the plate. firmly in the position andat the height which it thus. assumes, a hollow plunger 9.60, isslidingly mounted for vertical movement. on a stationary piston. 2.62secured to the frame of the machine. A spring 264 connected to theplunger tendsto moveit downwardly and holds it initially in itslowestposition in engagementwith a boss 2E6 on. the, frame. Through a bore268. inv the piston 2&2. fluidunder pressure is admitted to the interioror the plunger 280 to move itupwardI-y into, supporting engagement. witha roimd portion of pin240 between. the rectangular portions 2'39 oi. thepin. Such admissionoi. the fluid is controlled by the samev previouslymentioned valve (not shown) which controls. the upperpulling movementsof the grippers,. the shoe at this time having already been clampedagainst the shoev rest members 2. and 6 by the toe rest 46. It. will beunderstood that the pressure thus applied to the plate 238' by theplunger. 2.60 is not. sufficient. to displace the. shoe from the.position in which it is. held. between the shoe. rest members 2 and 6and the toe. rest.

Further to insure against any tipping of the shoe by the actionof thebars 2I8 on the flexible wiper I18 mechanism is provided for. positivelylocking the plunger 256 against. downwardmovement after it has beenmoved upwardly... IThis echanism. comprises three pawls arranged instaggered relation for engagement with ratchet teeth 2'") onv theplunger. One of these pawls 212 is fast on a pinz'l'imounted to turnin-a bearing on the cylinder casting Thand. at opposite sides of thispawLrespectively, are two other pawls 21B loose on the pin. Each. of thepawls 21B. is controlled. by a small spring. 278.connected to it and toa pin 28!) extending through the pawl 2'12, these springs holding thepawls 2-16 initially in a. relation. to the pawl 212 determined by theirengagement with the pin 280, as shown in Fig. l. Mounted in the middlepawl 212 is a spring-pressed pin 282 in engagement with the casting Tiand tending to swing the three pawls toward the ratchetv teeth 219'. Thepawls are held initially out of engagement with the teeth by arod 284pivotally mounted at its upper end on a; pin: 286 in the. piston '58 andhaving fast thereon a collar 28.8 which initially engages an arm 29!!fast on the pin 214 and thereby holds the pawls in their idle positions.When the piston 10 is. movedupwardly to carry the toe rest it intoengagement with the shoe the upward movement of the rod 28- releases tharm 29:5 and thus permits the pawls to be swung into engagement with theteeth ziil'by the spring-pressed pin 2.82 ready to hold; the plunger 2%against downwardmovement after its upward movement. In the return of theparts to: starting positions the downward movement of the piston itcauses the rod 284 to withdraw the pawlsfrom the ratchet teeth, thuspermitting return of the plunger 260 by thespring 264 when the fluid isreleased from with- I in it. Upward movement of the plunger if there isno shoe in the machine is limited by engagement of a lug 292 thereonwith a stop 294.

Since the cycle of operations of the machine to which the invention isshown as applied is fully described in the previously mentioned earlierapplication, and since the manner in which the mechanisms provided bythe invention perform their functions has been hereinbefore fullydescribed, no further description of the operation is necessary.
